The project aims to generate viscoelastic soft materials with programmable anisotropy using aqueous suspensions of colloidal rods that have tunable surface coatings. The project expects to generate new knowledge in the rheology and structural characteristics of this unique class of materials. A key innovation is the use of charge-directed polymer self-assembly to control colloidal interactions, suspension rheology and phase behaviour. The intended outcome is spatial control over the orientation of nanostructures, potentially mimicking the structural hierarchy found in nature. This should provide significant benefits to the creation of viscoelastic materials with complex rheology as well as structural, mechanical and optical heterogeneity.

该项目旨在使用具有可调表面涂层的胶体棒的水悬浮液来生成具有可编程各向异性的粘弹性软材料。该项目期望产生有关此类独特材料的流变学和结构特征的新知识。一项关键创新是使用电荷导向聚合物自组装来控制胶体相互作用、悬浮液流变学和相行为。预期的结果是对纳米结构方向的空间控制，可能模仿自然界中发现的结构层次。这将为具有复杂流变性以及结构、机械和光学异质性的粘弹性材料的创建提供显着的好处。
